Hi
I have been searching alot about this topic, and all that i gathered is that the oneplus 6 is dual standby phone. This means that when on a call on SIM 1, then you are unreachable on SIM 2. I'm not talking about volte, but on GSM.
Also this means when I'm on a call on any SIM, the data shuts off unless I'm in area with duplex gsm channel then data drops back to H. (As per my friend who works in the teleco company here, cuz sometimes and in some areas when I'm on a call, the data doesn't drop back to H but rather completely shuts and in some areas and some times it drops back to H)
As per my reading, this happens because the oneplus 6 utilises the x16 chip which has a single antenna.
Here is where my confusion, i tried an out going call from SIM 1, put the call on hold, dial another number on SIM 2, conference the calls, Viola, it works. This means that i can use both SIMs actively.
Please someone shed some more light on this.
Note, I'm using 2 separate SIMs but from the same operator.
Also, im on the Android p beta 1 rom but have been able to do this on the previous OTAs also.
Cheers
Op6 is dual standby not dual active that means when you call from sim 1 sim 2 is inactive and vice versa.
I don't know which phone support dual active.

Hi
Try calling from SIM 1, hold the call, dial another number from SIM 2, conference the calls, you will see that the conference works, here is where i get confused because everyone says it's dual standby, so conferencing the calls shouldn't work

I think i figured out what's going on, when placing the second call, although I'm telling the phone to dial from SIM 2 it dials from SIM 1. so both calls are originating from SIM 1.

Def possible.
If I'm on a call on the first SIM, I can't even send a text message out on the 2nd.

Got a z3 dual. Was primarily interested with this because they said it was dual active and many users posted that when other sim is active for call the other sim is still open for data,sms and other stuff. Meaning it has 2 active lines but i am experiencing otherwise. When i received a call the other sim is inactive, there is an hoir glass symbol and when i tried texting by the other sim it just won't send because it's inactive. Who has a z3 dual here that can verify as well
Edit: here are pic of the signal bar while on call
Hi
Just got my Xperia Z3 DUO today.
I put 2 tmobile USA sims in the phone.
We are in a building with a Tmobile antenna on the roof so the service for every phone is rock solid full bars.
However, in my experia z3 duo, no matter which sim i put in as sim 1 (and I have tried 7 differnet sims) , the service is 2-3 bars in contrast to sim 2 which is full bars always.
Any ideas????
thanks
Eric
In your situation I think sim2 is 2G band with full bars and sim1 must be set for something higher, like 4G or 3G.
I also have z3 duo and with sim1 Lte a can get on sim2 only 2G. Sim1 also has default package transmission on, sim2 not.
Check this options in your phone.
I agree with Bino saw, the biggest annoyance I find with the Z3 DUAL is that you have to go into your cell settings and switch which SIM you want to be LTE/3G or 2G as only one SIM can be LTE/3G and the other has to be 2G. Go into your mobile settings and switch your GSM sim to LTE and see if it changes. (Note the switching the "Data" SIM under my dual SIM settings doesn't automatically change these settings for me, not sure if it's suppose to)
Hi everybody.
I hope someone can help me because I've been researching for months and I'm running out of options.
First, I need to have 2 lines active at any moment, one local and another from a foreign country, in roaming. Most of the available phones are dual standby, what means that when you get a call in one SIM the other one is disconnected. That's not good enough, because I need to know if someone calls me to the foreign number while I'm talking in the local number.
When both numbers are from the same country, some people configures call forwarding from one SIM to the other. That way, if one SIM is unavailable, you get the call in the other. But having 2 numbers from 2 different countries that solution causes more expenses, the call forward is an international call...
So I've been working with a dual active smartphone: a Huawei Honor 8, one of the last ones with 2 antennas. It's been working good, but the second antenna is only 2G, and 2G is being disabled in some places as 5G arrives. I totally understand that, it has to die as 1G died before. But it causes me a lot of communication issues.
Some options I've been looking for:
- A dual active smartphone with 3G in the second antenna. But I don't find any new dual active smartphones manufactured in the last 3 years...
- I read a lot about 4G dual VoLTE, but it seems to be dual standby. It seems that, during a call, it uses VoLTE to forward calls to the disconnected SIM over the 4G data connection in the enabled SIM, but I'm not sure if this will work with SIMs from different countries -although both providers support VoLTE.
- An external device that gives my phone a second SIM -like PIECE in Kickstarter, that never delivered-.
- A second dumbphone with the foreign SIM, only for getting calls, very long batter duration. But the options seem to be very few, and less 3G/4G...
So I'm running out of ideas. Do you know any modern dual active smartphone with 3G in the secondary SIM? Do you know if VoLTE works for call forward with SIMs from different countries? Do you have any suggestion of a good reliable dumbphone for the second line? Do you have any other solution I didn't think aboyt? Please please, help. I really appreciate it.

So everything I've read indicates that the 7 Pro is Dual SIM Standby. However a rep at OnePlus assured me that it is Dual SIM Active and couldn't figure out why I couldn't send or receive MMS messages from either SIM no matter which one was set to active. He escalated my case to the higher tech support to try to resolve. Is he indeed wrong or is the 7 Pro really Dual SIM Active? And if he is wrong and the device is Dual SIM Standby, is there a firmware or kernel mod that will enable both SIMs active?

It's dual SIM standby
Is anyone having issues with calls lately? I have 2 S22 Ultras (Exynos) and they both do the same thing. When you are in the middle of a call, whether it is 2 or 3 min in, or 10 min, all of the sudden you dont hear anything anymore but the call is still there. If you hung up and call again, the call doesn't even connect. I literally have to put the phone on Airplane mode, and take it off to reconnect again in order for calls to work again. Both phones are on VDA software.
I had this issue on my snapdragon U1. Apparently my sim card was the culprit. Did you try changing that?

Most probably issue with the network or the sim card. Try getting a new sim card from the provider first
I havent because its happening to both phones, not just one. I'll try giving the provider a call. Thanks.
I have the same problem. I changed the sim card and the problem is still there.
